EDWARD HUBER, OF MARION, OHIO.

STEAM-ENGINE GOVERNOR.

SPECIFICATION formingpart of Letters Patent No. 239,252, dated March 22,18811.

Application filed December 21. 1880.

To all whom it may concern:

Be it known that I, EDWARD HUBER, of Marion, in the county of Marion,and in the State of Ohio, have invented certain new and usefulImprovements in Steam-Engine Governors; and I do hereby declare that thefollowing is a full, clear, and exact description of the invention,reference being had to the accompanying drawings, and" to the letters ofreference marked thereon,inaking a part of this specification.

This invention relates to certain improvements in steam-enginegovernors; and it has for its object to provide a governor which may beattached directly to the hub of a disk or wheel of the main shaft of theengine, and suitable mechanism in connection therewith Whereby the throwof the eccentric may be varied correspondingly to the speed of theengine, and regulate the throw of the slide-valve This object I attainby the mechanism illustrated in the accompanying drawings, in which-Figure 1 represents a side elevation of myimproved governor, showing theparts complete. Fig. 2 represents asectional View through the disk andeccentric, and Fig. 3 represents a detached View of the curved bearin gsagainst which the gibs work.

The letter A indicates the disk, mounted on the shaft of an ordinaryengine, which disk carries the mechanism of my improved governor.

The letter 0 indicates a guide or way extending diametrically across theface of the disk, inwhich are adapted to reciprocate the sliding blocksD, secured to the eccentric E.

The letter F indicates two angle-levers, secured to the studs atdiametrically opposite points on the face of the disk, the longer armsbeing provided with governor-weightsB, the short arms being connected bylinks G with the projections H on the sides of the collar I, which isloosely mounted on the hubof the disk A, mounted on the main shaft ofthem- (Model) gine. The said projections on the collar are to theirseats by means of the arms II on the collar V, secured to the shaft W.The curved bearings are formed one nearer the center of the eccentricthan the other, so that when the collar is shipped by the operation ofthe governor-weight the eccentricity of the eccentric will be changed soas to vary the throw of the eccentric and the valve which it operatesaccording to the speed of the engine, and thus govern the admission ofsteam to the cylinder. The projecting arms can be used without gibs, andwhen thus constructed they must be made longer than when the gibs areused.

I do not claim, broadly, a governor consisting of a disk with leverspivoted thereto and provided with governor-weights, as Iarn aware thatsuch is old.

Having thus described my invention, what I I claim, and desire to secureby Letters Pat cut, is

In combination with the main shaft of an engine, the disk as described,the levers pivoted thereto and provided with governor- Weights, thecollar secured to the hub which connects the lever with said collar, andsaid hub provided with friction-arms having gibs, the eccentric operatedby said friction-arms, and the arms for confining the gibs to theirseats, substantially as and for the purposes specified.

In testimony that I claim the foregoing l have hereunto set my hand this20th day of November, 1880.
